Construction Containment for Live Data Centers That Cannot Go Down
Unplanned data center downtime costs as much as $9,000 per minute. Dust, debris, ESD contamination, and airflow disruption from construction are direct and preventable contributors to that number. 5DCCS provides modular containment systems engineered for mission-critical environments. Our walls are fast to install, debris-free at removal, and built to preserve the thermal and air quality conditions your equipment depends on.
Why Data Centers Demand a Different Standard
One Containment Failure Can Cost More Than the Entire Project
Live data centers operate under environmental requirements that have no parallel in conventional commercial construction. Airflow, temperature, humidity, electrostatic charge, and physical contamination are all actively managed within fractions of an inch of water column pressure and within single degrees Celsius. A construction activity as routine as drilling into a wall or removing a raised floor tile releases particulate matter and debris that can migrate into server intake paths, settle on circuit boards, and cause failures that look like hardware problems but are actually contamination events.
Uptime Institute's research found that 54% of significant data center outages cost more than $100,000, with 16% exceeding $1 million. Unplanned downtime can reach $9,000 per minute for large enterprises. Inadequate construction containment is a direct and preventable contributor to those numbers. The cost of proper containment is trivial compared to the cost of a single contamination-driven outage.
The Contamination Risks Construction Introduces
Dust, ESD, and Zinc Whiskers Are Not Hypothetical Risks
Construction generates gypsum dust, concrete particles, silica, metal fragments, and fine particulate matter. Particles as small as 2.5 microns which are smaller than what the human eye can see and lodge inside server enclosures and are difficult to dislodge without causing further damage. Electrically charged dust can cause signal disturbances, data loss, short circuits, and power failures. Dust blocking air vents forces cooling systems to work harder, increasing power consumption and shortening equipment lifetime.
Electrostatic discharge (ESD) is an even more insidious threat. Semiconductors can be damaged by discharge events at voltages as low as 100 volts — a threshold far below what workers can detect. Construction personnel moving across non-ESD flooring, using non-grounded tools, or contacting synthetic materials generate triboelectric charge that presents a real damage risk to live hardware. In raised-floor environments, disturbing floor tiles can also release zinc whiskers (microscopic conductive filaments that become airborne and cause intermittent short circuit failures when drawn into server hardware through cooling air paths).
Where We Work
Containment Solutions for Every Mission-Critical Environment
Every data center and controlled-environment facility has distinct uptime requirements, cooling configurations, and contamination sensitivities. Here is how we support active construction across the full range of mission-critical project types.
Active Data Hall Renovations & Expansions
Upgrades to live server rooms — CRAC unit replacements, power distribution changes, raised-floor modifications, cable tray additions — require construction to happen while adjacent racks remain in production. Our barriers isolate the work zone from live equipment, seal raised-floor plenum access points, and prevent particulate migration through the hot-aisle and cold-aisle cooling path during the entire duration of work.
HVAC & Cooling System Upgrades
Replacing or adding cooling infrastructure — CRAC units, in-row coolers, chilled water systems, or economizer upgrades — disrupts the airflow conditions that adjacent IT equipment depends on. Our containment systems maintain the thermal envelope around live equipment during HVAC work, preventing the temperature excursions that ASHRAE TC 9.9 guidelines warn against and that trigger thermal shutdown or accelerated hardware degradation.
Electrical & Power Infrastructure Work
Switchgear replacements, UPS upgrades, PDU installations, and generator tie-ins involve construction activity in or adjacent to the electrical infrastructure that supports live IT loads. Beyond fire and debris control, our systems help define a physical boundary for ESD-aware work protocols — containing construction personnel and their tools within a zone where grounding and anti-static practices are actively enforced.
Hyperscale & Colocation Facility Expansions
Large-scale data center expansions that add new halls or power zones adjacent to live operations require containment that can be reconfigured as each phase completes. Our modular systems accommodate phased buildouts without demolishing and rebuilding barriers — critical when the construction boundary moves every few weeks as new capacity comes online and old space is decommissioned or repurposed.
Cleanroom & Controlled Environment Modifications
ISO Class 7 and Class 8 environments used for data center operations, network operations centers, and high-availability computing require air cleanliness standards that standard construction practices immediately violate. Our barriers provide the physical separation required to maintain classified air quality in adjacent spaces while renovation proceeds, with HEPA negative air integration available for the most contamination-sensitive adjacencies.
Security Perimeter & Access Control Projects
Physical security upgrades — biometric access control installations, mantrap construction, security camera systems, and perimeter hardening — often require construction within the secure perimeter of a live data center. Our barriers define the construction boundary while maintaining the access control integrity of surrounding areas, controlling contractor personnel movement without requiring the facility to suspend normal operations or relax its physical security posture.
Technical Standards
The Framework Governing Construction in Live Data Centers
Data center construction sits at the intersection of fire protection, electrostatics, air quality, and IT operations — each governed by its own set of standards. ASHRAE TC 9.9 defines the thermal envelope within which IT equipment must operate. NFPA 75 and NFPA 76 govern fire protection for information technology equipment and telecommunications facilities. ASTM E84 establishes the minimum fire rating for any material used as a construction barrier inside a data center. Uptime Institute Tier Standards define the operational availability requirements that constrain how and when construction can happen in a certified facility.
Containment barriers are not passive infrastructure — they are active tools for maintaining compliance with these standards during construction. A temporary wall that violates the fire suppression volume calculation, allows particulate to migrate into live equipment, or disrupts the hot-aisle/cold-aisle thermal balance is not a containment solution. It is a liability. Our systems are specified to address all of these requirements, not just the visible ones.
Why Modular Walls
What Plastic Sheeting and Drywall Cannot Do in a Live Data Hall
The data center industry's own published guidance is explicit: never use standard drywall or plastic sheeting as the primary containment barrier in white space adjacencies. Both fail the performance requirements of the environment. Here is what modular walls provide that those alternatives cannot.
No Construction Debris — No Particulate Source
Drywall installation and removal generates gypsum dust that becomes a contamination source for live equipment. Our modular systems install without cutting, sanding, or generating airborne dust. When the project ends, panels are removed — no demolition debris, no dust cloud during teardown. The work zone closes without creating a secondary contamination event.
Maintains Hot-Aisle / Cold-Aisle Thermal Separation
Plastic sheeting tears and gaps under positive and negative air pressure, disrupting the differential pressure balance between hot aisles and cold aisles. Our rigid panel systems maintain their seals throughout the project duration, preserving the airflow dynamics that keep server inlet temperatures within ASHRAE TC 9.9 recommended ranges for adjacent live equipment.
HEPA Negative Air Integration for Critical Adjacencies
When the construction zone is immediately adjacent to live server rows, negative air pressure inside the containment enclosure prevents particulate from migrating into the hot-aisle return path. Our panels accept HEPA-filtered negative air machine connections through sealed ports, creating the pressure differential required to stop contamination at the source.
Supports ESD-Aware Work Zone Protocols
The physical barrier is the first layer of ESD risk management. By clearly defining the boundary of the construction zone, our systems support the enforcement of ESD protocols for all personnel and equipment entering the white space adjacency. The barrier is where grounding verification, ESD wrist strap checks, and tool inspections happen before access is granted.
ASTM E84 Class A — Required for All Data Center Applications
Data centers typically operate under clean-agent fire suppression systems calibrated to the protected volume. A barrier material that burns modifies the fire dynamics the suppression system was designed for. Every panel in our systems carries an ASTM E84 Class A fire rating — the standard required for construction barriers in occupied facilities with mission-critical fire suppression systems.
Reconfigurable as Phases Advance Without Downtime Events
Phased data center expansions require the construction boundary to shift as each zone comes online. Tearing down and rebuilding drywall between phases generates debris and takes time — both of which create risk in a live environment. Our modular systems reconfigure quickly and cleanly, keeping the construction footprint controlled and the exposure window to adjacent live equipment as short as possible.
